Drew Brees and the New Orleans Saints are road underdogs against the Vikings, but the line is moving against them despite public support. What does that mean for Drew Brees and company?

It's no secret that Vegas totals and spreads can be helpful when making fantasy football decisions -- especially in daily fantasy games.

Unfortunately, as professional NFL handicapper Warren Sharp has pointed out, Vegas' primary goal is not to set the most accurate lines -- Vegas' goal is to make money, and they do that by encouraging public action on a particular side. What does that mean?

Letâ€™s say Vegas opens the line on a game with Team X favored to beat Team Y by 7 points. If 80% of the public money coming in is in favor of Team X against the spread but Vegas still does not adjust the line, that demonstrates that either there is sharp money on Team Y or that Vegas feels confident about Team Y against the spread. Either way, by examining how Vegas is moving lines in comparison to where the public is betting, we can potentially gain an edge when making lineup decisions.
